630 PM CDT THU JUN 16 2016
.Discussion...
Issued at 313 PM CDT THU JUN 16 2016
Weakening MCV that tracked into western MO this afternoon disrupted
the influx of high moisture that lies just south of the area, and
therefore heat index values this afternoon have generally struggled
to reach 100 degrees. Still hot, but not quite heat advisory
criteria. Will therefore drop the advisory for parts of northern
Missouri for the rest of the afternoon, and keep it going further
south where temperatures have been a bit warmer.
Drier air has also led to a capped atmosphere across much of the
forecast area, enhanced by subsidence provided by the weakening MCV.
This will likely keep any chance for thunderstorms confined to the
Ozarks and areas southward overnight. Still can't rule out an
isolated shower across central MO late tonight in the vicinity of a
weak elevated boundary, but chances are rather low.
Weak front across the Mississippi Valley will nudge westward on
Friday, pushing the heat and humidity a bit further west into Kansas
and extreme western MO. Assuming no complicating thunderstorm
complexes form overnight, southeast flow into these areas should
allow the 70s dewpoints across southwest MO to advect into the
region. Combined with temperatures in the lower/middle 90s, this
should yield heat index values between 100 and 105, possibly a bit
higher south of KC. Will therefore keep the heat advisory going for
these areas through Friday evening.
Low level ridging across the Great Lakes will build a bit further
west over the weekend, sending the push of drier air further west
into the entire forecast area Saturday and Sunday. Highs will still
be in the lower to middle 90s both days, but heat index values will
be below 100.
Upper ridge will break down by Monday night, allowing a potentially
more active weather pattern to spread into the region. The first
system will arrive Monday night as a cold front moves in from the
north. This front will keep conditions relatively cooler through the
middle of next week with highs in the 80s.
